    _________58
    A:All
    B:Any
    C:Some
    D:Most

    答案：A
    解析：
    空格后的句子表明，生态学家正向公民科学家寻求帮助，可推测出每个地方不可能都有生态学家。故此处应选择A项。 everywhere每个地方；anywhere任何地方（通常用于疑问句或否定句）;somewhere某些地方；nowhere任何地方都不。
    此处表示：因为世界上有很多地方，但科学家的数量却不足，所以他们才寻求帮助。所以选择D项。if如果，倘若；although尽管；when当……的时候；because因为。
    气候变化的迹象需要人们进行“观察”。give给，给予；show展示；develop发展，开发； observe观察，观测。
    结合上下文可知，公民科学家运动鼓励一般人观察非常具体的研究对象。special特殊的；professional专业的；skillful熟练的；ordinary普通的，一般的。
    send…to…是固定搭配，表示“把……送往……”，符合题意。
    公民科学家帮助搜集数据，为数不多的气候学家就可以分析大量的数据。空格处应该是在强调数据量的庞大，因此选择D项。small小的，少的limited有限的simple简单的，朴素的large大的，大规模的。
    空格所在的句子把公民记者与公民科学家进行比较，表明他们的作用相似。much like 表示“就像……一样”，其中much修饰like，符合题意。very like与……很像，但不能用在句首，因此排除A项like与as都有“像……一样”的意思，若连用则意思重复，因此排除C项； many是形容词，不能修饰介词like，因此排除D项。
    第二段最后一句表明，要想成为公民科学家中的一员，需要做的全部事情就是每天或每周留出几分钟来搜集并发送数据。all全部，所有；any任何；some一些，某些；most大多数，大部分。
    根据第二段第三句可知，公民科学家搜集完信息后要将信息发往一个巨大的数据库，供专业科学家进行分析，所以此处选用send(送往，发送）。print打印，冲洗；answer回答；keep 保持，保留。
    此处表示被称为国家物候网络的组织，应该用called，表示事物与名称的关系。known 被知道，若要表示“被称为”应用known as ; featured有……的特征；belonged属于，是……的成员；called被称为，被叫作。
    这句话的大意是：这个团体最初的努力要依靠科学家和非科学家这类人去搜集花开叶落的信息。alike相似的，一类的（人或物），通常作后置定语；like相似的，一般作前置定语；un-like不同的; likely可能的，有希望的。
    本句大意是：花季追踪计划搜集美国各地的植物的生长周期的数据。而且四个选项中唯有data可以与collects（搜集）搭配。point观点，看法；wonder奇迹，惊奇；data数据；interest 兴趣。
    本句大意是：参与这一项目的人―这一项目对所有人开放―他们仅仅需要看看周围有什么。common普通的，平常的；suitable合适的；open开放的；strange奇怪的。
    don't have to是固定搭配，意思是“无需，不必”，符合题意。want想要；forget忘记；mind 介意。
    这句话的大意是：通过搜集数据，我们就能估算出植物和生物群落对气候变化会做出怎样的反应。how表示对方式的提问，用在此处符合题意。wh。谁，用来提问或连接先行词为人的定语从句；before在……之前；since自从，常用来引导时间状语从句，从句常用过去时，主句常用现在完成时。
